<P>PROBLEM TO BE SOLVED: To provide a combustion device in which blocking of an oil feed pipe due to tar or the like is prevented, vaporization pulsation due to the interval of dripping of liquid fuel is suppressed, a combustion flame is stabilized, and a wide combustion width can be obtained. <P>SOLUTION: In a liquid combustion device having a burner for burning premix gas with combustion gas and primary air mixed therein, a connection member with its one end connected to the oil feed pipe and its another end connected to a fuel diffusion member is provided, and the connection member is configured to be cooled by combustion air in an air supply chamber. With such configuration, heat of a vaporization part is hardly heat-transferred to the oil feed pipe, the occurrence of tar or the like due to remaining fuel in the oil feed pipe is suppressed, and blocking of the oil feed pipe can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
